Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground pin. Return for all internal circuitry and the low-side MOSFET source. Connect to the system ground plane with a low-impedance path. |+| 2 | LX | output | Switching node. Common connection of the internal high-side and low-side power MOSFETs; connects to the external inductor. Absolute maximum -0.3V to 20V (steady) / -4.5V to 22V (<10ns transient). |+| 3 | IN | power_in | Power supply input. 4.5V to 18V operating range (20V abs max). Bypass to GND with a low-ESR ceramic capacitor (22µF typical) placed close to the pin. |+| 4 | FB | input | Output voltage feedback input. Connect to the center tap of the external resistor divider between VOUT and GND. Regulated to VREF = 0.8V (TMI3253), 0.6V (TMI3253S), or 0.765V (TMI3253T). |+| 5 | EN | input | Enable input. Drive logic-high (>0.95V typ threshold) to enable the IC; drive logic-low to disable and enter micro-power shutdown (~5µA). Do NOT leave floating. |+| 6 | BS | passive | Bootstrap. A capacitor (typ 0.1µF) between LX and BS forms a floating supply that powers the high-side N-MOSFET gate driver. Absolute maximum 26V to GND, 6V BS-to-LX. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TMI |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TMI3253`+- `TMI3253T`+- `TMI3253S`++## CAD (KiCad official)++- Symbol: `TMI3253`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TMI datasheet](docs/tmi3253-datasheet.pdf) (16 pp, sha256 `b58c2a4a18985f81`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
